How to add advertisement node at the end of Slideshow

Question

I have three content type 1) Slideshow 2) Slides 3) Advertisement

While creating slideshow we can assign slides to slideshow with nodereference field. We have created a views for slideshow on the view page of slideshow we are displaying all the slides one by one and there are two links next and previous. Now I want to add a single Advertisement at the end of this slideshow view.

I tried hook_views_api() and hook_views_query_alter(). Content type slides and advertisements have different fields.

Answer 1

slides are usually images or maybe node bodies (html). It doesnt really matter that advertisments have different fields. I had some code in Drupal 6 you could adapt to D7 or your needs, look into hook_views_pre_render() ...

You simply want to load your advertisement node(s) before the view is rendered and add them to the end of the slideshow ... see below.

//d6 example
function MYMODULE_views_pre_render(&$view) {

  if ($view->name == 'your_view' &&
    $view->current_display == 'slideshow_xyz') {
    // Insert something to the end of the view results.
    // For example another "node" or advertisement.
    $some_node = node_load(array('nid' => 456));
    // make a fake view row item with your advertisement.
    // you should create all fields used in "slides" from your
    // advertisement node data.
    $advertisement_item = new stdClass();
    // add your advertisement fields as fields being used by the Slide view.
    $advertisement_item->a_field_views_is_using = $some_node->advertisement_field_1;
    //  ... add all other view row items you are using ....
    // make this advertisement "row" in the results appending to the view results for slides.
    array_push($view->result, $advertisement_item);
  }
}
